A study has been made of photoluminescence (PL) and electroluminescence (EL) from single-crystal n-type ZnSe:Al electrodes. It is shown that emission from the electrodes, with a measured radiative quantum yield of 0.1-0.01, competes favorably with other deactivation paths in stable efficient photoelectrochemical cells. As observed with other semiconductor electrodes, the PL of n-ZnSe:Al electrodes can be perturbed and EL initiated by interfacial charge-transfer processes. It is shown that PL quenching by applied potential is compatible with a dead-layer model used to describe such quenching in other photoelectrochemical cells and in Au-ZnSe Schottky diodes. 24 references.
